States of matter

At KS3 and KS4 we consider there are three different phases or states of matter (solid, liquid and gas). There are other interesting states that are considered elsewhere, such as plasma (which is an ionised gas that can conduct https://www.britannica.com/science/plasma-state-of-matter) and Bose-Einstein condensates (predicted in 1942 and only created for the first time in 1995, see more here).
